Black Hole Bangle

The event horizon of a supermassive black hole represents a boundary in the space-time continuum. Everything located behind it, is not perceptible from outside. Some cosmological models suggest the universe itself is enclosed by an event horizon. Fascinating! The Black Hole Bangle is embellished with a natural black opal. Its range of colours is diverse; almost all known colours are reflected in it. With all the light that a black hole is sucking up, I find the idea very charming that it could be just as colourful inside the black hole. The bracelet is decorated with a monumental inscription, in which one should slip into: The Event Horizon of a Supermassive Black Hole.

We pay great attention to the quality of our products! In order to present you with a great variety of colors and content, we use various techniques of goldsmithing. Since we want you to enjoy your piece of jewelry for a long time, we recommend to read and follow our care instructions.

Remove your jewelry before washing your hands, perfuming or moisturizing. The particles of these cosmetics, which can not be removed by short washing, can be deposited in hard-to-reach areas and become a corrosive mixture which can lead to premature wear of the metal in the long term.

This also applies to the use of household cleaners.

Avoid contact with salt water. This can attack both precious stones as well as precious metals and thereby sustainably damage.

Special care must be taken with pieces with fire-embers, since fire-seals are melted glass, which can break through an improper treatment.

Gold cladding may wear out over time, depending on the load. This is a natural process which, however, can be avoided by appropriate treatment (see above).

What materials are used at Jonathan Johnson?

Since sustainability is a very important topic for us, we only use recycled precious metals (gold, silver, brass), which we obtain from a Scheideanstalt in the southern part of Germany. For more information feel free to contact our customer service.

What`s the difference between fire enamel and cold enamel?

Fire enamel or “real enamel” is a natural product of melted glass, which develops a very special charm through its delicate and slightly irregular color, which results from the burning at high temperatures, which can only produce true enamel. Kaltemaille is a synthetic resin mixed with color pigments which hardens without heating.

Where do the diamonds come from Jonathan Johnson is using?

We receive our diamonds from Germany’s oldest diamond grinding mill, which basically only imports diamonds from legitimate sources of natural origin and is in line with UN resolutions 1171, 1173, 1306 and 1343.

How and where are the products manufactured?

The complete production is located in Germany. All products (jewelry) are designed and produced in our manufacture in Hamburg. Since the issue of sustainability is very important to us, we only work with a small warehouse and prefer to manufacture our jewelry on demand in order to conserve resources and to remain exclusive. Exceptions are some products that we do not produce ourselves but continue to distribute in a cooperation. Corresponding information about the country of origin can always be found on the product page under the item “Product details".

Black Hole

Where do we come from and what is the void and if it exists – is that our origin that we will return to? Where was the beginning? Maybe in the void. Maybe in the black hole that is mysterious to us and that we know nothing of, neither if it is the beginning of something new, nor if it is the end of everything.
